SPECIFICATION forming part of Inetters Patent No. 739,802, dated September 22, 1963.

Application filed June 7, 1901.`

To all whom, it may concern:

Beit known that we, J ons A. BRILL and WALTER S. ADAMS, citizens of the United States, residing in the city and county of Phil- 5 adelphia, State of Pennsylvania, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification. Y

Our invention relates to improvements in 1o car-trucks, and although not limited in some ofA its features to any one cial reference to those known as pivotal trucks and on which the propelling-motor is carried. Among its objects may be mentioned a very short wheel-base and at the same time a long springbase for the motor-supporting frame, a novel combined spring cap or pedestal, a new spring-support for the bolster, and a new and 2o improved truck which shall be durable, compact, and efficient for the purposes required. To the accomplishment of these objects and such others as may hereinafter appear the invention consists in the parts and combina- 25 tions of parts fully described, and set forth in the claims appended hereto, reference being had to the accompanying drawings, forming a part hereof, in which the same reference characters represent like parts throughin which-'- l 1 is a side elevation ofthe truck embodying our improvements. Fig. 2 is a plan View of the same. Fig. 3 is an end view, the left half being a cross-section on a plane subcenter of the truck. Fig. fi is a detailed perspective view of the connection of the transoms and side members of the frame and thebolster with its supports. Fig. 5 is an enlarged sectional view on the 4o line o; Fig. 6, showing the bolster-support at one end and taken the bolster. Fig. 6 is a similar view transversely through the bolster-.supporting bearings, and Figs. 7 and 8 are respectively elevation and plan views of another form in which the equalizing-bar spring is located within the wheel-base. Y

In the figures, 2 and 3 denote the axles and wheels of the truck, which are journaled in 5o the axle-boxes 4, the latter being formed with depending lugs 5, preferably formed integral Figure class they have spe` longitudinally through' Serial Nil-763.496. (No modali) therewith and provided with longitudinal apertures through which the equalizing-bars 6 extend and by'which they are supported and connected with the axles. The eqnalizingbars, as shown, are preferably rectangular in cross-section, placed on edge, and of such dimensions as to give ample strength and are simply straight iron bars from end to end,

which form results in a very simple and cheap bar, besides allowing a low-hung frame. The apertures through which they project in the bones have curved upper edges or faces 7 (shown in dotted lines in Fig. 7) to provide for a limited play in case one axle-box rises or falls more than another. These boxes are simple, and therefore cheap to manufacture.

The axle-boxes are connected with the truclrframe by means of the inverted-U- shaped axle-box pedestals or yohes S, whose vertical side members 9 and 10 embrace the said boxes in the usual or desired way, the axle-boxes, except in the respect mentioned, being of any ordinaryor preferred type, and whose outer depending arms 11 are connected together by the angle-iron end pieces or crossbarsi ofthe truck-frame, which are bowed or bent out, as at 12, toraccommodate the motor, the yokes being connected together on each side of the truck by the upper chords 13, bolted to the tops of the yokes, and the lower angle-iron chord 14e, also bolted to the inner depending arms 10a of said yokes, the said chords, and consequently the side frame, being braced by the inclined or truss bars 15, made,preferably, in one piece extending from the tops of the yokes,where they are secured by the same bolts as the chords 13, down to the middle of the lower chords and are bolted thereto. To render this connection4 convenient, the yoke-s, which are cast, forged, or otherwise constructed, are grooved or slotted on top, as at 8a, to -accom modate the said chords and braces and are provided with short inwardly-extending arms 10a, adapted to be bolted to the outwardly-extending horizontal flanges 14a of the lower chord 14e. The -side members 9 and 10 of each yoke are rigidly connected together to strengthen them by the removable tie-bar 16, and which may be detached to allow the boxes to be removed therefrom. So far as some features of the invention are concerned the side members of the frame maybe constructed integrally with the yokesv or otherwise, but are preferred as shown.

The yoke-frame is spring-supported from the equalizing-bars b, and as a means'for simply and conveniently doing this the pedestals 8 (see Fig. 7) are provided with inaXle-box openings, although a slight web may be interposed, if desired, said recess 17 being located over the said equalizing-bar, which carries a base block or cap 18, secured thereto by a bolt and provided, if desired, with a between which cap and lug and the of the inverted cup 17 the coil-spring 19 is placed. The vertical arms 10 of the pedestals are cut away or notched, as at 20, Fig. 3, and the inner cylindrical wall ot' the recess 17 may be likewise cut away to allow the truck-frame to move down over the equalizing-bar when the spring is compressed. ay

being provided beaxle-boxes and the corresponding space 202L tween the tops of the yokes. An opening 21 is also provided in the cup-wall. This combined construction of the pedestal and spring-recess renders it a strong, cheap, and simple means for accomplishing the desired ends, besides servingr as a covering and confining means Vfor said springs, and dispenses with the extra bearing-block for the frame similar to the block 18 on the bar 6. These equalizing or ear on the inner side of sible to provide a more extensive spring-base forthe truck-frame. 'lhedescribedconstruction allows the springs to practically abut the boxes. In other constructions, as where a short wheel-base is preferred and the motors are supported outside the same, it is desirable to also support the motor-frame outside the wheel-base to provide a steadier support for the motor. The construction shown in Figs. 1, 2, and 3 offers a convenient method of so locating the springs and at the same and spring-cup structure. Here the equalizing-bar 6 is extended through and beyond the axle-box beneath the spring-recess `17, formed in the outer arm 11, a block 18 being secured tothe end of the bar to support the struction is substantially sleeved upon the axles andare supported at their heels or free ends from the cross-bars 22, spring-supported atvtheir ends upon the end bars 12 of the truck-frame, their ends being twisted to stand horizontally and perfopass over bolts 23 and depressed, as at 23, tov'raise the supporting parts above the anges of the angle-iron end pieces 12. Coilsprings are placed both above and below the ends of the motor-support on the bolt 23 to cushionl its movement in either direction. This feature of supporting the free end o'f a motor inside or outside of the wheel-base on a frame which is itself spring-supported outside the wheel-base we consider broadly new and intend so to claim it. This motor-supporting frame need not be 'the yoke-frame, but may be any otherA suitable for the purpose. Of course it will be understood that trucks, as shown, may be constructed, or one set of springs may be placed inside the wheelbase and the other outside thereof.

In order to pivotally connect the truck with the car-body, a novel bolsterarrangement and connection is provided. The bolster 24, consisting, preferably, of a stick of timber, as shown, having the usual pivot or center plate 25 and side bearing or rub plates 2G, extends transversely of the frame and is confined between the angle-iron transoms 27 and 28, also extending between said side frames, each with a vertical web against the side of the bolster and the horizontal `web on top and extending away from the bolster. The side bearing or rub plates 26 may be adjustable in height, as shown, and are preferably those shown and described in the patent to YValter S. Adams, bearing date of September 16, 1902, and numbered 709,071. The horizontal webs of these transoms are bolted to the top chords 13 of the side fram-es, while the vertical webs are secured by the bolts 29 tobrackets 30, formed integrally on the vertical side members of rectangular braces or supports 31, which are securely held between the top and lower chords of the side frame, said brackets projecting inwardly along the side of the transoins 27 and 28, the ends of the boister 24 being recessed, as at 32, to give room for the said brackets. These rectangular frames 31, under which the braces 15 are adapted to pass, are of cast or wrought iron and are grooved at the top and bottoni to it said upper and lower members or chords of the side frame, to which they are securely bolted. I They also have a web 31a with an elliptical aperture therein. This connection of the transoms with the other parts makes a most substantial and rigid construction'.

The novel means for ilexiblysupportiug the bolster consists of links or link-bars 33, capable of a slightswinging movement, which are suspended from pins 34, journaled in bearing-plates 34, bolted on top of the horizontal flanges or webs of said transoms, near the ends thereof, holes 33a therethrough being provided for the saidlinks,which extend IIO beneath the said `bolster for some distance, and the opposing ones are connected together by pivot-bolts 35, on which are journaled (see Fig. 5) the ends of the upper halt of an elliptic or semi-elliptic spring 36, the middle point of which bears against and may be secured to the under side of the bolster.

The spring 36 of course extends longitudinally of the bolster, as shown, and bears up.- ward against it, substantially at its middle point. As a means of securing it thereto, if such construction is preferred, the means shown in Figs. 3 and 4c may be employed, which means consists of the plate 36, attached to and let into the under side of the said bolster 24' and having a socket 36, adapted to receive the central band 36C of the elliptic spring 36. Other means could obviously be utilized. To assist in su pporting the bolster 2e, coilsprings 37 are placed between the said bolster and pivot-bolts 35, centering-lugs and pivot-plates 38 being provided near its ends for the top of the springs, while corresponding. lugs and blocks or saddles 39 are pivoted on the bolts or pins 35 for the lower ends of the coil-springs 37, which blocks 39 are hollow or, as shown,

straddle the ends of the elliptic springs 36.

The links, as shown, are bossed at the ends to provide a longer bearing on their pivotins. The bolster is thus spring-supported at the ends and at the middle, conjointly act in such supporting capacity, and at the same time either the end set or the middle spring is capable of performing that function alone, whereby an added security against total disabling is provided should one set fail, and a better-acting bolster throughout is obtained. This method of supporting a bolster in its broadest embodiment we consider novel. Several longitudinal springs could of course be used side byside, or the coil-spring might be replaced by others, or even a complete set of such springs of slightlysmaller size could be placed at each end of.

the bolster', but all such modifications and changes we consider within the limits of our improvements.

It will be apparent to those skilled in the art that various and many changes from the described construction may be made and still fall within the bounds of our invention, and we therefore do not wish to be limited to such construction; but
